How to use pfsense as a transparent sniffer only

[crevettedragon]

Hi,

Here is my use case: I want to upgrade my current internet box with a pfsense box. However, the traffic between the tv box and the internet box is special and I want to investigate it to be able to properly configure my pfsense box.

As such I want a “sneaky” pfsense that will simply log all traffic and act as a simple Ethernet cable from the internet and tv box perspective.

What would be the best way to do it ?

Why wouldn’t you just use a switch with a mirror port there and do whatever you want with the traffic? Wireshark, tcpdump, etc.

Certainly easier than trying to be transparent with a proxy.

You don’t need to hammer a square firewall into that round hole.
